Abstract

We examine how euro area (EA) monetary policy and recipient-country prudential policy interact to influence cross-border lending of French banks. We find that monetary spillovers via cross-border lending can be partially offset by prudential measures in receiving countries. We then explore heterogeneities, specifically by bank size and location of the affiliate (French HQ vs. affiliates based in the UK). We find that the response of lending from French HQ to EA monetary policy is less sensitive to recipient-country prudential policy for systemic banks (GSIBs) than for non-GSIBs’. In contrast, the response of lending from GSIBs’ affiliates in the UK is sensitive to recipient-country prudential policy. French GSIBs’ cross-border lending from French HQ responds differently than lending from international financial centres. We also find evidence that French GSIBs channel funds towards the UK in response to EA monetary policy, in a manner dampened by global prudential policy setting. These findings suggest the existence of a ‘London Bridge’: conditional on EA monetary policy, French GSIBs adjust their funds in the UK depending on global prudential policies and, from there, lend to third-party countries according to local prudential policies. Finally, we have similar findings for all EA-owned banks UK affiliates, suggesting a broader relevance for the London Bridge.
